Hello Sir,
We are facing an issue with upgrade process in our product, Installation was success but some of the files were not installed properly. This happened in Windows7 64 bit OS, installation was done with Admin privileges. New files were shipped successfully. Instead of older database upgrade new database was replaced after upgrade.
Below is the error we got in installation logs.
